BOILER-FRONT.

specification of Letters Patent.

Application filed May 1, 1914. Serial No. 835,688.

1 b all whom it may concern Be it known that if, Josnri-r S. Wncs'inn, a citizen of the United States. and a resident of Minneapolis, in the county of Hennepii'i and State of liiinnesota. have invented a new and useful. improvement in Boiler- Fronts, of which the following is a specification.

My invention relates to improvements in boiler fronts for tubular boilers; and the objects of my invention. are. first, to provide easy access to each tube or flue without interfering with the draft of any excepting the tube or tubes being cleaned; second. a removable front which may be readily attached to a boiler without materially affecting its continuous service; third. the extension of lower portion of front to connect With a removable receptacle for removing the soot; and fourth, to provide for the removal of all or part of my invention for repairing flues. etc. I attain these objects by the mechanism shown in the accompanying drawing in which- Figure 1 is a sectional view of my boiler front applied to a common horizontal tubular boiler, showing a flue cleaner inserted through a trap-door in my front; Fig. 2 is a front view, showing trap door openings, hinges, cable clips, and position when applied to boiler with common style of doors; this also Shows position. of front when attached to an old boiler, or when regular doors are retained; Fig. 3 a sectional view of one of the trap-doors when closed; and Fig. 4 shows a view of trap door when open.

Similar letters refer to similar parts throughout the several views.

In Fig. l, A represents a flue-cleaner mounted on rod B inserted in flue C through trap-door opening D in front E, a trap-door F being open for the insertion of the cleaner; a. bushing 0 may be inserted into opening D for cleaner rod to pass through. to more effectively prevent interference with draft. H is a handle on front G of soot re ceptacle l. M is a weight to facilitate raislng of front when necessary to repair fines. In Fig. 2 one of the trap-doors F is shown "open. exposing opening D in front E; cable clips 2' cnd b and hinges d and a. are shown: K is the fixed piece of hinge, the other portion being formed as a part of trapdoor. a pin being provided for each trap door sup ported by the said fixed piece; front G of soot receptacle overlaps front 1E and is provided with handles 1 i and il Fig. 3 is a sectional View of trap-door F when closed, and Fig. -:i a sectional view with trap-door open.

For convenient a pplication to an old boiler in. articular. I prefer first to bend an angle iron to form about two-thirds of a circle, fasten same inside the extended head of boiler. and bolt my device to same.

It is apparent that the openings D must register with boiler fines and be of suitable size to correspond with same. It is also apparent that the draft may be effectively regulated by opening any desired number of trap-doors.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent:

1. A removable front between front doors of smoke arch and tube sheet, said front having openings registering with. the tubes, and trap-door closures for said openings, substantially as shown and described.

2. A. removable front between front doors of smoke arch and tube sheet, with openings registering wvith the tubes and trapdoor closures for said openiitigs, in combination with a soot receptacle, the omrlapping front of said soot receptacle completing the inclosure under said removable front, all sub stantially as shown and described.
